DNA scanner

Gene expression data processing method and processing program

The variation of the data collected from a DNA chip is adequately detected and the variation is corrected if possible. In a gene expression data processing method of collecting analyzable data by processing array data acquired according to the expression level of the genes on a DNA chip, the DNA chip is divided into small regions. Data values constituting the array data are standardized (step 300). The average value of the standardized data values or the standard deviation of the median is calculated (step 310). It is checked if there is any variation of the data collected from the DNA chip on the basis of an increase of the standard deviation (step 310).

Dna sequence analyzer and method and program for analyzing dna sequence

It is intended to provide a technique whereby an abnormality in genomic DNA sequence copy number can be identified at a high resolution and a high reliability. Based on control tag data and analyte tag data, data corresponding to the control tag data and the analyte tag data is compiled. By using this corresponding data, analyte tags corresponding to individual regions on the genome are counted to detect the occurrence of chromosomal abnormalities (amplification, deletion, etc.) in individual region on the genome. The data relating to amplification, deletion and so on in the individual regions on the genome can be highly useful in identifying, for example, a disease gene.

Method of detecting relation between genes

A method of detecting a relation between genes involving the step wherein a partial correlation coefficient is approximately determined with the use of regression analysis in association with selection of variables to thereby eliminate effects of an arbitrary third gene on a first and second genes among a large number of genes. Thus, the relation between the first and second genes can be found out without affected by any other gene. This method is useful in analyzing the expression profile of genes obtained by DNA microarrays.

Laser scanner and method for controlling a laser scanner

The invention relates to a 3-D laser scanner, wherein a camera is integrated into a rotating head. Color information is scanned by means of the camera, such that a color image of the measured object is achieved in combination with the laser data.

Scanning method and scanner for detecting a radiation emitted by a measurement object

The invention relates to a scanner for detecting radiation, notably radioactive radiation, which is characterized by very high local resolution and permits short measurement times. The scanner can advantageously be used in nuclear medicine, for example in thyroid diagnosis accompanying an iodine-131 therapy.

Method for laser-processing a surface

The invention relates to a method for laser-processing a surface. A laser beam is guided over the surface by means of a laser scanner, and the surface is moved and/or rotated relative to the laser scanner in a plurality of sequential repositioning processes. During each repositioning process, the laser beam is deflected by the laser scanner along a directional path between a starting direction and an end direction over the surface. The surface is moved during each repositioning process at least in a positive acceleration phase, in which a speed of the surface relative to the laser scanner is increased, and a negative acceleration phase, which is carried out after the positive acceleration phase and in which the speed of the surface relative to the laser scanner is reduced to zero. When the speed reaches zero during the negative acceleration phase before the laser beam has reached the end direction, the speed increase during the positive acceleration phase of the subsequent repositioning process begins at the point in time when the laser beam reaches the end direction, and when the speed reaches zero during the negative acceleration phase after the laser beam has reached the end position, the speed increase during the positive acceleration phase of the subsequent repositioning process begins immediately after the speed has reached zero.

Method for embodying dna structure in article and article thereof

A method for embodying a DNA structure in an article by imprinting or configuring after analyzing a man's gene and extracting a portion of the analyzed gene, so that the imprinted or configured article can function as a unique identification mark of an article occupying man, and the article thereof. The method for embodying the DNA structure in an article, including the steps of: analyzing the DNA structure of a specific or plural persons related with each other by a DNA analyzer; displaying the analyzed DNA structure of a specific or plural persons on a displaying unit; editing the displayed DNA structure; and embodying the edited DNA structure in the article.
